First Lady Michelle Obama laughs with Stephen Colbert during her appearance on Comedy Central's "The Colbert Report."

First Lady Michelle Obama appeared on Wednesday's edition of "The Colbert Report" to discuss her new initiative with Dr. Jill Biden: Joining Forces, a program designed to assist military families and help veterans find employment after returning from tours of duty.

Stephen Colbert, adopting a slightly toned-down version of his standard schtick, couldn't help but steer the conversation back to himself.

"The last time you were here you were not First Lady—and now you are," Colbert said. "That's called the Colbert bump."

Later, Colbert grilled the First Lady on a key issue of the 2012 presidential campaign: Nickelodeon's "iCarly."

"As someone who has both appeared on my show and 'iCarly,' which of us has more gravitas?" Colbert asked.

The First Lady didn't provide a definitive answer, but played along with the gag.
